Intense light bent out of shape—ultrafast lenses made from gas

Researchers from the MPIK in Heidelberg used an atomic gas as a time-dependent lens to shape and spectrally manipulate intense high-frequency laser pulses. This gas-based optical element could pave the way toward better XUV- and X-ray pulse control for applications such as chemical reaction steering, quantum computing, and advanced spectroscopy methods for fundamental science. The paper is published in the journal Science Advances.
